Gravitational Wave Astronomy with the SKA [PDF]

Proceedings of Advancing Astrophysics with the Square Kilometre Array — PoS(AASKA14), 2015
On a time scale of years to decades, gravitational wave (GW) astronomy will become a reality. Low frequency (nanoHz) GWs are detectable through long-term timing observations of the most stable pulsars. Radio observatories worldwide are currently carrying out observing programmes to detect GWs, with data sets being shared through the International ...

Quantum metrology for gravitational wave astronomy [PDF]

Nature Communications, 2010
Einstein's general theory of relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves (GWs) have not been directly detected to date, but are expected to open a new window to the Universe once the detectors, kilometre-scale laser ...

Introduction to Gravitational Wave Astronomy [PDF]

, 2021
This chapter provides an overview of gravitational wave (GW) astronomy, providing background material that underpins the other, more specialized chapters in this handbook. It starts with a brief historical review of the development of GW astronomy, from Einstein's prediction of GWs in 1916 to the first direct detection in 2015.

Gravitational wave astronomy: needle in a haystack [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013
A worldwide array of highly sensitive ground-based interferometers stands poised to usher in a new era in astronomy with the first direct detection of gravitational waves. The data from these instruments will provide a unique perspective on extreme astrophysical objects, such as neutron stars and black holes, and will allow us to test Einstein’s theory

Swift/UVOT: 18 Years of Long GRB Discoveries and Advances

Universe, 2023
The Neil Gehrels Swift Observatory (Swift) has been in operation for 18 years. The Ultra-Violet/Optical Telescope (UVOT) onboard Swift was designed to capture the earliest optical/UV emission from gamma-ray bursts (GRBs), spanning the first few minutes ...

3D characterization of low optical absorption structures in large crystalline sapphire substrates for gravitational wave detectors

Scientific Reports, 2021
Very high-quality sapphire substrates are key elements of the cryogenic Japanese gravitational interferometer KAGRA, in which they are used to build the main mirrors, working as the test masses to sense the gravitational waves.

GRAVITATIONAL WAVE ASTRONOMY [PDF]

Annual Review of Nuclear and Particle Science, 2004
▪ Abstract  The existence of gravitational radiation is a direct prediction of Einstein's theory of general relativity, published in 1916. The observation of gravitational radiation will open a new astronomical window on the universe, allowing the study of dynamic strong-field gravity, as well as many other astrophysical objects and processes ...

Gravitational wave astronomy with TianQin

Reports on Progress in Physics
Abstract The opening of the gravitational wave window has significantly enhanced our capacity to explore the Universe’s most extreme and dynamic sector. In the mHz frequency range, a diverse range of compact objects, from the most massive black holes at the farthest reaches of the Universe to the lightest white dwarfs in our cosmic ...

Attitude-Orbit Coupled Control of Gravitational Wave Detection Spacecraft with Communication Delays

Sensors, 2023
In order to meet the position and attitude requirements of spacecrafts and test masses for gravitational-wave detection missions, the attitude-orbit coordination control of multiple spacecrafts and test masses is studied.
